VENTiLATOR.

SPECIFICATION forming part of Letters Patent No. 462,604, dated November 3, 1891.

Application filed June 18, 1891. Serial No. 396,754. (No model.)

To all whom, t may concern.-

l-Se it known that I, THOMAS UTLES?, engineer, a subject of the Queen of Great Britain, and a resident of Stoneycroft, Liverpool, England, have invented certain new and useful Improvements in and Relating to Ventilatore chiefly designed for use in connection with ships side lights, (for which I have obtained a patent in Great Britain, No. 17,422, dated November 29, 1888,) ot which the following is a specification, reference being had to the accompanying drawings.

My invention relates to ventilators chiefly designed for use in connection with the cabins, holds, and other eompartm ents of ships,where ventilation is essential or desirable; and my said invention comprises improvements in the ventilators described in the specification of a former United States patent granted to myself and John Fawcett, No. 301,538, dated .Iuly S, 188i.

An important feature of my present invention consists in providing for the ventilation of two or more cabins, compartments, or holds through a single side-light port or other opening, or the ventilation of one cabin, compartment, or hold through more than one aperture. For this purpose I combine with the side-light port or other opening, one or more air-chambers, each provided with a iioat or valve, or with a set of lioats or valves, and I connect the said chamber or chambers by means of snitable pipes, passages, or apertures with two or more cabins, compartments, or holds. In some instances, however, I apply my present improvements to apparatus for the ventilation of a single cabin, compartment, or hold.

Another important feature of my said invention is the combination, with a single sidelight port or other opening, of two or more separate or distinct air-chambers provided with floats or valves, and so constructed that, should the valve or valves in one chamber get out of order, this chamber can be closed without preventing or interfering with the action of the other chamber or chambers. I thus obviate the necessity for discontinuing the use of the ventilator,in case one valve or set of valves shonld'become inoperative through leakage or otherwise.

My said invention, moreover, comprises other improvements hereinafter set fort-h.

Patented in England November 29, 1888, No. 17,422.

In the accompanying drawings I have shown how my said invention may be conveniently and advantageously carried into practice.

Itigure l is a front elevation,partly in vertical section, and Fig. 2 is a vertical section on the line a' a',Fig.1,some of the parts being shown in side elevation showing' myimproved ventilator.

Like letters indicate corresponding parts thro ughont the drawings.

A is the wall or side of the vessel. B is the side-light port or opening. C is the interior side light.. D is the shutter therefor.

a is a casing divided by partitions u into compartments or air-chambers. These airchambers are in communication on the ontside of the vessel with the open air through the side-light opening or port B, (or other con- 7o venient Ope11ing,)and upon the inside by means of apertures b, provided with flnid-tight doors c with one or more cabins, holds, or other parts of the vessel which it is desired to ventilate.

"When my improved ventilator is applied to a side-light port the side light C is preferably inclined, as shown in the drawings, for the sake of economining,` space and obtaining' as much light as is practicable.l

Each air-chamber is provided with horizontal partitions d, having suitable apertures c for the passage ot air, and provided with iioats or valvesf for preventing the admission of water through the said apertures e in the event S 5 of the side light or port B being temporarily immersed, substantially as described in my said former specification. The valvesf are provided with vertical spindles or guides r/ g', and are so arranged that they can move freely 9o to or from valve-seatings 7L in the horizontal partition d. The `:guide g is attached to the upper float or valve f, andis adapted to move freely in a hole c' in one of the cross-pieces or cross-bars e2, which are firmly attached to 95 or form part of the partitions d. The lower cross-piece or cross-bar e2 serves to support the upper extremityof the spindle or guide g, the lower extremity of which is supported in a bracket g2, attached to the side of the chamroo ber a, and the lower valve f is arranged to move freely up and down on the said spindle or gnideg. The floats or valves f are preferably provided with valve-rings or washers j",

of india-rubber or'other suitable material intended to bear against the seatings 7L when the said ioats or valves f are raised by water entering through the port B.V These rings or washers can be easily and expeditiously replaced when desired.

By dividing the casing d into two or more distinct air-chambers, I am enabled in case of leakage or for other reasons to shut oft' one or more of the said chambers, leaving the other chamber or chambers open for the admission ot air. The partitions d in some instances extend downward from the top of the aircha1n bers to or below the lower horizontal partitions d, or down to the upper edge of the side, light or other opening or port, as shown. In other instances they are arranged so that the portion of each vertical partition below the upper horizontal partition d is dispensed with. It is preferable, however, that the casing d should be divided throughout its entire height, as otherwise (in cases wh ere two or more cabins, compartments, or holds are ventilated through a single ventilator) a greater quantity of the air which passes through the casing might be drawn into one of the said cabins, compartments, or holds than into another of the same, thus causing deficient ventilation of the latter.

It is obvious that I can employ any suitable number of air-chambers in connection with a single sideflight er other convenient port or opening in the side or other part of the vessel. It is obvious, moreover, that I can s0n1ewhat further modify the construction of my improved ventilator without departingvfrom the nature of my saidinvention. Forinstance, I can employ other suitable floats or valves,

and means for guiding the same. I can, if desired, employ a single valve in each aircha-mber, suitable means being provided, as hereinbefore described, for permitting the closing of one air-chamber while leaving the other chamber or chambers in operation. Moreover, I can, if desired, applymy improvements to ships ventilators provided with a single Valve, so that the air from a single sidelight or other opening may be conducted to two or more holds or compartments.

"IV hat I claim is-' 1. A ships ventilator consisting of a casing divided by a vertical partition into two distinct air-chambers located side by side, a vertically-movable float-valve arranged in each air-chamber, and a pair of independenttluidtight doors at the upper portions of the airchambers for delivering air to separate cabins or compartments, whereby either one of the air-chambers may be closed independent of the other, substantially as and for the purposes described.

2. A ships ventilator consisting of a casing divided by a vertical partition into two distinct air-chambers, a side light located below the divided casing, and a vertical1y-movable Heat-valve located in each air-chamber, substantially as and for the purposes described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing'witnesses.
